DUIVIPING-VEHICLE.

Specification of Letters Patent.

Patented Nov. 20,1906,

Application filed February 13,1905. Serial No. 245,429.

To all whom it may concern.-

Be it known that I, JOHN HOVAS, of New York, in the county of New York and State of New York, have inventedcertain new and and odor that usually accompany the use of a.

vehicle of this character when it is filled.

The invention consists, primarily, of a vehicle or cart of this character having a normally closed body provided with feed-openings covered by both inwardly and outwardly opening doors, said doors swinging in different planes and covering diiferent areas of the feed-opening and so arranged that when one being door is opened'inwardly by the attendant pushing an ash-can or similar receptacle thereagainst to empty its contents into the cart an adjacent door will open outwardly, so as to allow the distribution of the refuse to the best advantage, as will be hereinafter more specifically described. a

In the accompanying drawings, Figure 1 is a perspective view of a cart embodying the improvements of my invention. Fig. 2 is a similar view illustrating a slight modification. Fig. 3 is a detail view showing an inwardly-opening door and an outwardly-opening door and the device whereby the latter is opened by the former. Fig. 4 is a detail perspective view of a portion of one of the inwardly opening doors and its device for swinging an outwardly-opening door. Figs. 5 and 6 are detail views illustrating features of the inwardly-opening doors looking at the inner side thereof. Fig. 7 is a detail view of one of said latter doors and the joint-strip for the same shown detached. Fig. 8 is a perspective View illustrating the end-gate in open position and the unlatching-lever detached.

The body 1 of the cars is designed to tilt to discharge its load and is preferably construct-,

ed'throughout of sheet metal. It is entirely and permanently closed, except a dischargeopening in its rear controlled by an end-gate and'side openings, preferably in both sides, controlled by swinging doors 2 and 3, in this instance four in number, on each side of the body. These doors are arranged in two pairs, the one door of each pair contiguous to the end of the body being hinged at its upper edge to swing outwardly to open and the other doors being contiguous to each othei at the middle of the body and being also similarly hinged to open inwardly. The inwardly-swinging doors of each pair is hinged to swing in a different plane from its complementary door, as seen by reference to the drawings, the two doors covering different areas of the opening. In other words, each door in closed position covers only a part of the feed-opening. Each of the doors is normally held and returned to closed position by a spring 4.

The two inwardly-opening doors 3 are, as shown, of considerably less width than the outer doors 2 and are pivoted at a. lower plane than the latter. Each of the doors 3 is provided with a bracketed arm 5, projecting above its pivot and carrying two rollers 6, one eccentric to the other, said rollers being designed to contact with the inner face of the adjacent outer door below the hinge thereof. Hence as a middle door 3 is swung inwardly the rollers 6 will constitute a cam bearing against the adjacent outer door and will cause the latter to swing outwardly, as indicated in Fig. 3. The vertical edges of the outer doors 2 preferably overlap the corresponding edges of the inner or middle doors 3 for the purpose of forming a dust-tight oint, and as the meeting vertical edges of the two middle doors 3 must necessarily lie flush with each other I have provided for a similar purpose a ointstrip 7, hinged at its upper end'to lie across said edges against the outer faces of said doors, which are recessed at their upper corners, as shown at 7 Fig. 7, to accommodate the hinge portion of said strip.

The end-gate 8 of the cart is hinged at its upper edge and is provided with an eccentrically-pivoted latch-bar 9, designed to rock into engagement with hooks 10 on thebody 1. To rock the said bar out of engagement with the hooks, I have provided an unlatching-lever 11, which lies adjacent one of said hooks in contact with the projecting end of the bar. The latch-bar is limited in its movement by stop-pins 12. A rule-joint strut 13 is provided to hold the end-gate in open position while the load is being discharged.

It will be observed that in Fig. 1 the endgate is located below the meeting flanges 14, that secure together the upper section or top 1 of the cart-body to the lower or bottom section l thereof, While in Fig. 2 the endgate forms a part of said upper section. The object of showing these two different con.- structions is that Fig. 1 illustrates a cart as it would appear if constructed outright with my invention in view, while Fig. 2 illustrates how my invention may be applied to an already-constructed open-top sheet-metal cart of the kind now commonly employed. In the latter instance the invention prac-. tically constitutes a closed cover for a cart.

In practical use the cart is filled by the attendant resting the ash-can or other receptacle on the ledge formed by the flanges 14 and tilting it against one of the small middle doors which open inwardly will effect a proportionately greater outward movement of the adjacent end door, so that the can may be rolled toward the end of the body and emptied and the refuse may thus be heaped up at the two ends of the cart before the middle portion is filled to such a height as to interfere with the opening of the middle doors. With this arrangement the attendant is not required to open any door by hand, his hands being engaged with lifting and tilting the can, and, furthermore, as only the two comparatively narrow doors swing inwardly and as it is only necessary to swing them open to a small extent to effect the opening of an outwardly-swinging door to a reater extent the body of the cart may be filed to a capacity more commensurate with its area than is the case with those carts that are provided with doors all of which swing inwardly.

The end-gate 8, its latching means, and the devices controlling the same constitute the subject-matter of a separate application for patent, filed August 9, 1905, Serial No. 273,359.

I claim as my invention 1. In a vehicle of the class described, a body rovided with a feed-opening, doors hinge to swing in different planes transversely of said opening and covering different areas thereof, and means operated by the withdrawal of one of said doors from the o ening for effecting a similar movement of t e other door.

2. In a vehicle of the class described, a body provided with a feed-opening, an in wardly-opening door and an outwardlyopening door designed to cover different areas of said opening and each hinged to swing in a different plane from the other transversely of said opening, and means oper ated by the opening of one door for efiecting the opening of the other.

3. In a vehicle of the class described, a body provided with a feedopening, an inwardly-swinging door and an outwardlyswinging door hinged to swing vertically in different planes transversely of said opening and covering different areas thereof, and a connection between the two doors whereby the movement of the former to open will ef-' ic pct a corresponding movement of the other oor.

4. In a vehicle of the class described, a body provided at its side with four verticallyswinging doors each hinged to swing in a different plane from the others and at right angles to said side, two of said doors opening outwardly and two inwardly and the latter being located between the former, and means operated by the movement to open each of the inwardly-opening doors for ef-' fecting a corres onding movement of the adjacent outward y-opening doors.
